United States Patent SELF-MITERING EFFECT OF KNITTED TUBU- LAR BRAID TO FORM A CORNER Morris M. Langa, Philadelphia, Pa.

Application March 7, 1955, Serial No. 492,513

1 Claim. (Cl. 2-278) My invention relates to braid applied to fabrics, and relates particularly to the use of knitted tubular braid sewed Or embroidered in spiralling angular pattern to obtain a pleasing and decorative appearance.

When woven or plaited braid is used, the braid turns up at the corners, does not lie flat, and shows an unsightly upthrust, or protuberance, overlap, or fold; thereby marring the appearance of the corner.

It, therefore, is an object of my invention to produce an ornamental corner of a knitted tubing on fabrics wherein the corners of the tubing lie flat and undistorted because of the self-mitering effect of the knitted tubing when stitched along one side to the fabric.

Other objects of my invention are to provide an improved device of the character described, that is easily and economically produced, that is easily and economically applied, and which is highly effective in its application to fabric material.

With the above and related objects in view, my invention consists in the details of construction and combination of parts, as will be more fully understood from the following description, when read in conjunction with the accompanying drawings in which:

Fig. 1 is a view of a piece of fabric and a knitted tube itself.

Fig. 2 shows the knitted tubular braid sewed to the fabric to form a spiraling pattern.

Fig. 3 is a sectional view taken along the lines 3-3 of Figs. 2 and 5.

Fig. 4 is a very large view showing the knitted tubular braid with its loops as it is stitched upon a piece of fabric. There is a highly exaggerated view with the loops being bunched together where there is a narrow radius of curvature or a sharp bend, and the loops are spread when there is a large radius of curvature.

Fig. 5 is a plan view of the knitted tubular braid stitched to a piece of fabric wherein a spirally angular pattern is illustrated.

Referring now in greater detail to the drawing, wherein similar reference characters refer to similar parts, I show a piece of fabric material, generally designated as A, and a knitted tube or tubing termed a knitted tubular braid, generally designated as B, which forms a corner or angle on the fabric A.

The knitted tubular braid is sewed to the material A to form an ornamental type of corner by means of a series of stitches passing through the tubing and the fabric. It is found that the corner formed thereby is sharpwithout rise or overlap-and lies fiat and undistorted upon the fabric.

It is found that the unsewed edges B1 of the knitted tubular braid B forms a clean corner at 11 where the direction of the braid B reverses itself.

Woven or plaited braid cannot satisfactorily be used, since it becomes distorted when formed into a corner.

In Fig. 4, I show the knitted tubular braid B sewed along edge B2 by a series of stitches 10 passing entirely through the tubing, the interior of the tubing when flattened, and through the fabric, leaving the tubular braid as an attractive, undistorted angle. As the stitching 10 passes entirely through two overlapping portions of the tubing B and the fabric A, the tubing will be flat upon the fabric.

The row of stitching 10 holding the knitted tubular braid to the fabric A preferably should be on the outside of the corner or angle, and the row of stitching at the corner or angle should not be more than when the angle is measured on the inside. Hence, the row of stitching of the angle measured on the outside of the corner or angle should be more than 180.

The knitted tubular braid B serves to have the loops telescope or be intermeshed, as at 11, Fig. 4, at the short radius curve, and the loops are extended or stretched, as at 13, Fig. 4, at the greater radius corner curve. The forementioned intermeshing of the tubular braid results in the self-mitering of the braid to' form an undistorted corner.

The row of stitches 10 pass entirely through the fabric A and the flattened sides of the knitted tubular braid B, as shown in Figs. 3 and 4, to obtain the hereinbefore mentioned desired result.

In my Patent No. 2,703,406 granted March 8, 1955', I disclose a knitted tube attached to a fabric.

Although my invention has been described in considerable detail, such description is intended as being illustrative rather than limiting, since the invention may be variously embodied, and the scope of the invention is to be determined as claimed.

I claim as my invention:

In combination with a fabric, a flattened knitted tubular braid having a plurality of intermeshing loops, said tubular braid being arranged in a series of whorls and sewn flat to the fabric by a single line of stitches extending longitudinally with said braid, said stitches passing entirely through said braid and said fabric whereby opposite longitudinal edges of said braid form a plurality of concentric curve pairs, each curve pair having inner and outer arcs whereby the intermeshing loops adjacent each inner are are bunched in compression and the intermeshing loops adjacent each outer are are protracted in extension, thereby alleviating stresses at the longitudinal edges of the braid and permitting the braid to lie flat upon the fabric in a relaxed configuration.
